"lot of people are intimidated by the ukemi or dont know how to take ukemi for this technique."

I think that the problem is simply lack of practice, and therefor fear of the ukemi.

one thing that I've found effective is to have students spend more time loading up (2-3X loading and then 1X throw) that way uke can get used to it, nage can work on position, and there's less wear on the body.
